Title: Measuring method for speed of vehicle
Inventor: YAMADA TAKAHIKO
IPC: G01P3/64
Filed: 1980-08-12
Abstract: PURPOSE:To select the correct measured value of the vehicle speed in vehicle speed measuring devices using two sensing means which are separaed by a specified distance, by judging whether the vehicle has run in parallel with a traffic lane or not based on difference in sensed times and each sensed time. CONSTITUTION:The vehicle 1 runs on a road 7a and passes over sensing regions 2 and 3 of the first and second vehicle sensing devices. The sensing regions 2 and 3 are separated by the distance L. The running speed is obtained from the rise time difference DELTAT of the sensed output. If the vehicle does not run in parallel with the lane, as shown by a course 6, the rise time difference does not correspond to the distance L correctly. Let the sensing time for the vehicle at sensing regions be T1 and T2. The measured value is selected by a ratio of T1-T2 and the rise time difference DELTAT. Thus inadequate measured values are eliminated.

Title: Laser doppler speedmeter
Inventor: TAMAKI TERUYUKI
IPC: G01S17/58
Filed: 1990-04-27
Abstract: PURPOSE:To simplify a control mechanism by making the scattered light of a laser beam incident upon a sweeping type confocal Fabry-Perot interferometer successively through an optical lens, an optical fiber, an optical lens, a polarizing element, and a photocoupler. CONSTITUTION:Respective scattered beams converged by respective convex lenses 5 are polarized by respective polarizing elements 6 so that respective polarizing faces are made vertical to each other. These polarized scattered beams are coupled by the photocoupler 7 and made incident upon the sweeping type confocal Fabry-Perot interferometer 8. A light intensity output from the interferometer 8 is detected by a photodetector 9, its electric signal is amplified by a lock-in amplifier 10 and the speed of a moving object is found out by a speed computing element 11 based on the amplification signal and a sweeping signal obtained from the interferometer 8. Since the speed is not influenced by a distance between the moving object and the speedmeter, the preparation of a mechanism for controlling the distance is unnecessary.

Title: Radiant tube burner
Inventor: HIRASAWA FUSAO
IPC: F23C3/00
Filed: 1983-06-20
Abstract: PURPOSE:To prevent the burn-out of a valve and to improve the efficiency of mixture of fuel gas and the air for combustion, by a method wherein a support plate, a flow passage for the air for combustion, and a fuel gas flow passage are installed, and a combustion chamber is located separately from valves for the air for combustion and fuel gas. CONSTITUTION:The air for combustion frocibly opens an air valve 34 through an air guide hole 31 and admits an air flow passage 28a, and flows through an air injection nozzle 28. In which case, the fuel gas, forcibly opening a gas valve 40 through a gas pipe 27 and admitting a gas flow passage 26, is fed through a gas injection nozzle 29 to an air injection nozzle 28 to be mixed. Thereafter, by energizing an ignition plug 24 to discharge spark in a combustion chamber 22a, air-fuel mixture is ignited for explosion combustion. The combustion chamber 22a is separated enoughly away from an air valve 34 and a gas valve 40, and a retainer plate 25, an air flow passage 28a, and a fuel gas passage are located therebetween, and this reduces the combustion influence, exercised on each valve, of air-fuel mixture, resulting in prevention of the occurrence of the burn- out.

Title: Temperature-sensitive control valve
Inventor: SATOMOTO ATSUSHI
IPC: F16K17/38
Filed: 1979-08-30
Abstract: PURPOSE: To permit smooth and reliable operation without sacrifice of the sealing property by forming the spring of a bimetal disc which is thermally deformed to open and close the flow path with the bimetal material and thus obtaining proper inhanced force in accordance with the temperature.  
     CONSTITUTION: A housing 6 is formed with first and second ports 2 and 3 and flow paths 4 and 5 therefrom and both the paths 4 and 5 are communicated by a space 8 formed in a body 7. A bimetal disc 9 provided in the space 8 is deformed in accordance with the temperature to be brought into close contact with an elastic seal 11 for closing the flow path 4. A bimetal spring 10 which urges the disc 9 has a plurality of arms 14 projecting from a central part 13. With temperature increase these arms are contracted to weaken the enhanced force so as to prevent fixing of  the disc 9 and seal 11 to each other, while with temperature reduction they are  extended to make up for the reduction of the elasticity of the seal 11. Thus, the  flow path can be smoothly and reliably opened and closed either at the time of  closure at a high temperature or at the time of opening at a low temperature.

Abstract: PURPOSE: To eliminate the need of separate oxidation equipment through enhanced absorbent utilization factor, prevention of gypsum scale deposition, and gypsum production in absorption equipment by a method wherein air is blown into the absorption equipment to make oxgen concentration in gas higher there than in waste gas itself.  
     CONSTITUTION: A waste gas having high content of SO 2  is humidified and freed from dust in a cooling tower 2, then is guided into the first absorption tower 7 where the gas contacts, at pH 4, lime slurry reacted to some degree, supplied from the second absorption tower. Either fine bubble generator is installed in a liquid sump 11 or air is directly admitted to the inlet 11' of the absorption tower, so that oxygen concentration is increased in the tower to effect completion of absorbent reaction to produce gypsum. Part of slurry circulated from the tower 7 is passed through a settler 14 and a centrifugal separator 15 to recover the gypsum 16. Overflowed liquid 17' and filtered liquid 17 are sent to raw-lime-slurry control tank 19. Waste gas from the tower 7 enters the second absorption tower 8, where SO 2  is removed by high-absorbent slurry of pH more than 6, supplied from the control tank 19, and is discharged.

Title: Sealed type squid fluxmeter
Inventor: KAYANE KAZUO
IPC: G01R33/035
Filed: 1990-04-26
Abstract: PURPOSE:To improve durability due to a temperature cycle and to prevent a protection film from being deteriorated by moisture in air by sealing a SQVID element formed by a thin film into a sealed structure on a silicone substrate. CONSTITUTION:This fluxmeter is constituted of sticking the SQVID element 1 formed by the thin film to epoxy resin 2 and drawing terminals 3 from the center part of one side of the resin structure. The surface of the epoxy resin is covered with an epoxy resin box 4 and both the resin components are stuck to each other with an epoxy thermosetting material 5. The sealing of the element 1 is executed in a pressure reduced state or in gaseous He atmosphere. Even when the temperature of the fluxmeter is restored from the liquid He temperature to a room temperature, the protection film can be prevented from being deteriorated by moisture in air. Since the temperature is not suddenly reduced or increased, the element can be prevented from being deteriorated due to the temperature cycle.

Title: Visual sensation apparatus produced by using free radical polymerizable latent uv absorbent
Inventor: MOLOCK FRANK F
IPC: C07C49/83
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To make efficiently and conveniently producible a visual sensation apparatus containing a UV absorbent by using a compsn. containing a monomer which forms a visual sensation apparatus and containing a latent UV absorbent in an effective amt. for absorption. SOLUTION: The visual sensation apparatus is partly or wholly consists of a compsn. containing at least one kind of monomer which forms a visual sensation apparatus and containing a latent UV absorbent in an effective amt. for absorption. The UV absorbent means a compd. or compsn. which can absorb UV rays or shield from UV irradiation. In the latent UV absorbent, the functional groups reactive with UV rays in the UV absorbent are protected so that the absorbent does not react with UV rays or reacts only as little as possible. But the UV absorbent can initiate polymerization by UV rays with the monomers for the formation of the visual sensation apparatus. Thus, by preparing a latent absorbent by using a protective agent, the monomer for the formation of the visual sensation apparatus and the UV absorbent efficiently initiate free radical polymn. with UV rays.
